Ummm, could you translate the error messages to English please?
I am *guessing* that you are using version 0.5.7 of RSPerl, which contains C files hardwired to Perl 5.0's XS. Unfortunately the guts of Perl has changed much since then, you just can not expect perl XS to be backward compatible with older versions. And from what I see, the guts of R has also changed dramatically since then...
You could try to fix RSPerl's C files by resolving each error one-by-one. Probably not... Why don't you email an request to the Author of RSPerl and ask him for the upgrade?
Anonymous Monks's suggestion looks good...
Comment on Re: Re: Re: Social network analysis and Perl
Never mind the messages, it's just about missing files, and lots of other warnings and stuff... I just wanted to show there are lots of error messages. And yes, that was my hunch.
I'd rather write a social network analysis module in Perl myself than fix somebody else's C code. But I'll email him, anyways. Using R from perl is a good idea.
